BloodBank | A simple android project for blood management system | Android library

I have two tables BloodBank(id, name, phone, address) and BloodStock(id, a_pos, b_pos, a_neg, b_neg, bloodbank_id). I want to fetch all the columns from two tables where the variable column name (say bloodgroup) which have values like a_pos or a_neg... like that and their value should be greater than 0. How can I write ORM for the same?

SQL query is written like this to get the required results.

I am using laravel collctive form. I want to update only the quantity field of the following form keeping the blood_id field readonly. When I submit the form I am not getting blood_id value.

How can i solve it?

I am making a blood bank app and i am experiencing a problem in which I can't map my list of data in react native JSX. I copied most of the code from my todoApp that I made in react native earlier and modified it. I also want it to get all the data automatically when a user opens the app instead of manually using a button.

APP.JS:

I'm trying to count the blood type for each blood bank I'm using oracle DB the blood bank table is created like this

I have a very frustrating error that I cannot explain. I created an Android application that uses Androidx AppCompat to make it compatible with older versions. Here is my main activity layout file: {Androidx}.

here is my java file:

I'm creating a BloodBank application using c# and MySQL and my trouble right now is that I want to create a query with DATEDIFF() function that can calculate the difference in days between a made donation already and a new one from the same person since the same person can only donate blood 60 days after a previous donation. One of the dates is already in my MYSQL database and the other one will be received from a datepicker in a Window form .Net.

I have problem making the connection between the mysql database row for the current person and the info in the new made donation.

At the end I want to check if the difference between donations from a same person(same name and email in my case) is more than 60 days and in that case he can make a donation again.

I'm trying to scrape this website to prepare a database for blood donation camps using python.

Firstly, while trying to get the website html source code from requests or urllib there is a SSl:certificate_verify_error which i have bypassed by setting verify parameter as False for requests.get() or creating unverified context for urllib (a quick fix), this gets me past the error, but when i see the retrieved source html code, the table content that i need is empty, in website source they are included in the tbody tags but my requests.get() command gets me only these tags and not the content in between them. I'm very new to scraping, a little guidance would be appreciated. ty

After fill all the fields , submit button doesn't work and cancel also do nothing.

This function in my _.aspx.cs code:

I am trying to get Location on Button Click in my RecyclerView.

But When I click on the button the application crashes giving me this error
